Caporegime
If you're anywhere near failing on your first day, you've set your weights FAR too high.
The fist few sessions should be easy. Have you read up on how to use the programme?
I took the weight value as the mid point of my first week of the 5/3/1 mesocycle, however that didn't take into account the fact that I haven't squatted and done deads on the same day in months.
I have re-calculated my deads based on managing 2 reps at 90. So I have rerun the spreadsheet and it comes out at 82.5.
I managed the squats and bench without a problem - guess I just set my sights too high too soon!
What's your thoughts on the Heavy Squats on preceeding days?
To echo this, programmes such as SS and SL always start you light, so you can get your form right and then progress properly. Not that I've read up on SS, but on SL, they basically say you shouldn't really stall on your first 12 weeks if doing it properly (although that purely depends on diet, rest etc).
I'm not going into SS and SL from having no lifting experience, I did SS and SL for 5 months, and then switched to 5/3/1. I deloaded my squats in that time to work on the form, so I'm pretty comfortable with my form (with the exception of last weeks slight discomfort).
